If the lysosome and cell membrane were missing from the animal cell would the cell
be able to maintain homeostasis?
No, because the lysosome and the cell membrane aren't needed
Yes, becuse the lysosome and the cell membrane aren't needed
No, because the lysosome and the cell membrane are needed
Yes, because the lysosome and the cell membrane are needed
Answer: No, because the lysosome and the cell, membrane are needed.
If cells didn't have a membrane, the cell would just melt everywhere. If we didn't have lysosomes, there would be a lot of toxins in the cells.
Hope this helps :)
Potatoes can be genetically modified so that they are _________ to plant-eating beetle?
A. Toxic
B. Tacky
C. Tasty

What is the approximate percentage of guanine in the DNA genome of E. coli?
Answer:
25%
Explanation:
The approximate proportion of G + C content in the genome of E. coli has been reported to be 50%. According to Chargaff's rule, the amount of guanine in any DNA must be approximately equal to the amount of cytosine. Hence,
if G + C = 50 and G = C,
then
G = C = 25
Therefore, the approximate percentage of guanine in the genome of E. coli would be 25.
Which ecosystems would you expect to have the greatest access to sunlight?
A) open ocean and lakes
B) lakes and muddy rivers
c) kelp forests and open ocean
D) muddy rivers and kelp forests
E) springs and kelp forests
PLS HELP ASAP!
Answer:
A (?)
Explanation:
A) An open ocean has direct sunlight almost always, unless if it's night time, meaning that the surface would be open to sunlight whenever necessary. A lake also has more clean water, meaning sunlight can easily go through the water
B) A lake or a muddy river would likely also have direct access to sunlight, however, it could be covered easily by trees or other vegetation. And the mud in the river would likely make it difficult for sunlight to pass through.
C) A kelp forest likely blocks large amounts of sunlight because of their large structures and the tops usually grow outwards, meaning large amounts of sun would be covered.
D) See B and C
E) A spring is usually hidden in a forest, meaning it would possibly be difficult to collect sunlight due to the heavy vegetation and large trees that usually surround them.
This question is somewhat difficult to answer because most of these can be seen anywhere, meaning some can get sun while others can't, so it's hard to determine. Sorry if I got it wrong!
Answer:
A) open ocean and lakes

PLEASE HELP!! WILL GIVE BRAINLIEST
Answer:
People born first or last in a family have a different perspective than people born in the middle. Research has indicated that firstborn children are more likely to be achievement-oriented and responsible than later-born children. Later-born children on the other hand, tend to be better in social relationships and to be more affectionate and friendly. Other studies suggest that first-borns are conservative in their thinking and are defenders of the status quo. Later-borns, in contrast, are often risk-takers and social and educational rebels.
You over hear another student say "the human body is very efficent and wastes no energy." Using
what you understand about the process of cell respiration would you agree or disagree. Defend your
answer.
Answer:
I would disagree.

Animals that have analogous structures probably (choose 2)
A. evolved from the same common ancestor
B. are headed for extinction
C. are not related
D. evolved in the same environment
(I WILL GIVE BRAINLIEST)
Answer:
Explanation: For example, the wings of a fly, a moth, and a bird are analogous because they developed independently as adaptations to a common function—flying. The presence of the analogous structure, in this case the wing, does not reflect evolutionary closeness among the organisms that possess it.

A year has 365 days because that is the number of whole days it takes
the Earth to:
Q7) Why do we need to have a leap year once every four years?
Answer:
It takes approximately 365.25 days for Earth to orbit the Sun — a solar year. We usually round the days in a calendar year to 365. To make up for the missing partial day, we add one day to our calendar approximately every four years. That is a leap year.
Answer:
1. complete a 360 degree rotation.
2. circle around the Sun.
3. Every four years, we add an extra day, February 29, to our calendars. These extra days – called leap days – help synchronize our human-created calendars with Earth's orbit around the sun and the actual passing of the seasons. ... Blame Earth's orbit around the sun, which takes approximately 365.25 days.
